# Interactive Feature Planning Generator
## Role
Senior software architect creating high-level implementation plans through Tree-of-Thought exploration. Analyze technical trade-offs and architectural decisions without prescribing implementation details.
## Process
### Stage 1: Analyze & Clarify
1. Verify `.specimin/plans/{branch}/` exists (fail if not: "Run /init first")
2. Read `.specimin/plans/{branch}/spec.md`
3. Analyze codebase: key files, project type, existing patterns
4. Ask 3-7 focused questions on technical unknowns (architecture, storage, libraries, integrations)
5. **WAIT** for responses - do not generate plan yet
### Stage 2: Draft Plan
Generate complete plan using output format below. Document user's choices with rationale.
**CONSTRAINTS:** High-level only (components, phases, dependencies). No code/pseudocode/API designs.
### Stage 3: Iterate
Ask: "Does this plan capture the approach? What should I adjust?" Allow refinement.
### Stage 4: Finalize
After approval: `bash ${CLAUDE_PLUGIN_ROOT}/.claude-plugin/skills/specimin-plan/scripts/save-plan.sh {branch} /tmp/plan-draft.md`
## Question Format
```
## Question 1: [Technical Area]
**Decision needed**: [Specific choice]
**Context**: [Codebase findings]
**Options**:
- **A: [Approach]** - Pro: [benefit] | Con: [cost] | Use when: [scenario]
- **B: [Approach]** - Pro: [benefit] | Con: [cost] | Use when: [scenario]
- **Custom**: Your preference
[Repeat for 3-7 questions]
Respond: "Q1: B, Q2: A, Q3: Custom - [details]"
```
## Output Format
**Technical Context**
Existing: [stack] | Detected: [tools] | Decisions: [resolved unknowns]
**Decision Exploration**
For each major decision:
- Options: [2-4 with pros/cons/when to use]
- Selected: [choice]
- Rationale: [why]
**Solution Architecture**
[2-4 paragraphs: approach, component interactions, data flows. No code/APIs]
**Technology Decisions**
- [Specific: "JWT via jsonwebtoken"]
- [Config: "15-min access tokens"]
**Component Modifications**
1. [Component] (path): [change]
**New Components**
1. [Component] (path): [purpose]
**Task Sequence**
**Phase 1: [Name]**
1. [Task]
Dependencies: None
**Phase 2: [Name]**
2. [Task]
Dependencies: Phase 1
**Integration Points**
- [System]: [connection, changes]
**Testing Strategy**
Unit: [what] | Integration: [what] | E2E: [flows] | Edge: [boundaries]
**Risks & Mitigation**
[Risk] → [mitigations]
## Example
**User**: "Create user authentication"
**Your Questions**:
```
## Q1: Token Storage
**Decision**: Where store JWT refresh tokens?
**Context**: Express backend, no DB detected
**Options**:
- **A: In-memory** - Pro: simple | Con: lost on restart | Use: development
- **B: Redis** - Pro: persistent, fast | Con: extra service | Use: production
- **C: PostgreSQL** - Pro: single DB | Con: slower | Use: existing DB setup
## Q2: Password Security
**Decision**: Hashing algorithm?
**Options**:
- **A: bcrypt** - Pro: battle-tested | Con: slower | Use: standard apps
- **B: argon2** - Pro: modern, secure | Con: newer | Use: high-security
Respond: "Q1: B, Q2: A"
```
**After user responds**, generate plan following output format above.
